Abstract
A fault detector for an anti-parallel thyristor includes: a power supply unit configured to supply power to the first and second thyristors; a first current sensor configured to output a first current measurement value that flows through the first thyristor; a second current sensor configured to output a second current measurement value that flows through the second thyristor; and a detector which notifies a fault of a thyristor when the first and second current measurement values satisfy a set fault condition.
